Common faults and what to check first
Actuator does not respond to open or close commands
Check supply, local selector and fuses, then the control board. A failed power or logic board is a common cause.
Position or torque fault
A faulty position sensor, potentiometer or torque sensing circuit. Note the alarm shown on the display.
Display blank or garbled
Display or logic board faults. Send the label photo and describe what is displayed.
Motor runs hot or trips
Check the mechanism and torque setting first. A motor with failed insulation or bearings needs repair.

- Nameplate photo showing model and serial number
- Alarm or fault shown on the display
- Description of what the actuator does or does not do
- Control type (analog, Modbus, Profibus, hard-wired)
- Whether the board only or the whole unit will be sent

Frequently asked questions
Do you repair Rotork and AUMA actuator electronics?
Yes. We repair control boards, power boards, display boards and motors for Rotork, AUMA, Limitorque, Emerson and other electric actuators. Send the nameplate and the fault and we confirm repairability.
Do you repair smart valve positioners?
Yes. We repair smart and electro-pneumatic positioner electronics from makers such as Siemens, ABB, Samson and Emerson. Send the label photo and the symptom.
Can I send only the electronic module, not the whole actuator?
Often yes. For many faults the control or power module can be removed and sent on its own. Tell us the actuator model and we advise what to send.
Do you handle obsolete actuator electronics?
Yes, where circuits and parts allow. Send the nameplate and fault and we tell you what is possible and whether a replacement is the safer route.
What information do you need to quote?
The nameplate photo (model and serial), the fault or alarm, and whether the unit is electric, pneumatic or electro-hydraulic.
Is an actuator repair safe for a safety-critical valve?
Repaired electronics are tested before return. For safety-instrumented functions, keep your own proof-test and validation procedures in place after any repair.
How long does repair take?
Timing depends on the fault and parts. Send the nameplate photo first and we confirm repairability and timing before you ship.
